MARGIN INDICATOR.

Application filed September 8, 1920. Serial No. 408,916.

To all whom it may concern Be it known that UNION B. WHITE and HAROLD N. LAWRIE, citizens of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Margin Indicators, of which the following is a specification.

This invention relates to margin indicators for typewriters, and has for its object the production of a simple and eflicient device, which may be readily attached to or detached from a typewriting machine.

Another object of the present invention,

is the production of a margin indicator which may be easily-adjusted for use with the long or short type of letter sheet, or with the standard legal sheet.-

A still further object of this invention, is

g the production of a margin indicator, which will, at all times, keep the operator advised as to the number of lines remaining at the bottom of the sheet, upon which he is writing, and thereby permit an even margin to be maintained along the bottom edge of the typewritten sheet.

With these and other objects in View, this invention consists of certain constructions, combinations and arrangements of parts, as will, be hereinafter fully described and claimed.

In the drawing:

Fig. 1, is a perspective view of the margin indicator, removed from a typewriting machine.

Fig. 2, is a fragmentary perspective view of the body of the indicator, with the adjustable indicator and stop removed.

Fig. 3, is a longitudinal sectionalview of 40 the upper end of the indicator, showing the manner of attaching the stop to the adjust; able indicator.

I Fig. 5. is'a detail perspective view of the lower end of the stop, showing the underside thereof.

Fig. 6, is a perspective view of the adjustable indicator which is carried by the bodv of the indicator.

Fig. 7, is a perspective view showing the manner of attaching the marginindicator to the paper rest of one of the standard typewriters, such as the Underwood.

Fig. 8, is a perspective view of a modified.

form of the means for attaching the margin indicator to a straight paper rest.

Fig. 9, is a perspective view of a modified form of the device, showing the rear face of the body of the indicator the track-ways of the body, within which the adjustable 1ndication travels being provided with sprin tongues, for holding the adjustable indicator in an adjusted position.

By referring to the drawings, it will be seen that 1 designates the body of the indicator, which is provided with a longitudinal slot 2, the body 1 having track-ways struck from the sides of the slot 2, as indicated at 3. An adjustable indicator 4 is slidably mounted in the track-ways or flanges 3, and these track-ways are preferably formed of spring metal as illustrated in Fig.4. The trackways or flanges 3 are formed by folding the metal back upon itself along the edges of the slot 2, and then reversing the fold so as to provide a channel 4. The adjustable indicator 5, isslidably mounted within the trackways 3 and has its side edges fitting in the channels 4, shown also in Fig. 4. 30

A stop 6 is carried by the adjustable indicator 5, and this stop 6 is provided with a tongue 7 bentunder the body of the stop and extending at an angle thereto ;'a plug or filler 8 fitting between the tongue 7 and the 35 stop 6, as shown in Fig. 4 and constituting a brace for the stop 6. This plug 8 may be soldered to the under face of the stop 6, and suitable rivets or screws 9 pass through the adjustable indicator 5, the tongue 7 and into 0 the plug 8 for securely fastening the stop 6 to the adjustable indicator 5. The stop 6 comprises a plate which tapers toward its upper end, although it should be understood that it'is not desired to limit the device to any particular shape, The tongue? is the same width as the slot 2 in the body 1, but the stop 6 extends beyond the sides of the slot 2, so as to overhang the body 1 and permit the lower edge of the stop 6, as indicated by the numeral 10, to act as an abutment or stop for letter sheets of the long or short type, according to the adjustment of the stop 6. The upper end of the stop 6 terminates in an upstanding rolled portion, conmi stituting a finger grip 11. ,The lower end of the finger grip 11. is also rolled to form a bearing 12. The stop 6 may'also be formed of spring metal, thereby causing the rolled bearing l2 to frictiona-lly grip the face of 1m the body 1 and assist in holding the adjustable indicator in a set position.

Preferably, the body 1 is colored in contrast to the face of the stop 6, but it is not desired to limit the present disclosure to any particular color, although the body 1 may be colored red, the stop 6 green or blue, and the adjustable indicator 5 may be white.

A scale 13 is arranged to the right of the slot 2, upon the face of the body 1 and consists of a series of transversely extending graduated lines numbered from top to bottom as 1 to 10. The line numbered 1 starts at a point next below a line drawn in align ment with the upper edge of the-slot 2, as shown in Fig. 2. The stop 6 may be adjusted to the desired point upon the scale 13, in order that the'lower edge of the stop might act as a mechanical abutment against which the upper edge of a letter sheet may abut, thereby advising the operator that the sheet should be removed from the typewriting machine, in order that a proper margin might be left at the bottom of the sheet. The legend Long is placed upon theright ofi the stop 6 near'the lower edge thereof, just above the scale 13. designating the scale which should be used in connection with letter sheets ofthe long type. The legend Short is likewise placed upon the left.

lower edge of the stop 6 to indicate the scale which should be used in connection with letter sheets of the short type.

A scale 14 is arranged to the left of the slot 2, and is numbered from 1 to 10 beginning with the fourth line from the top. This scale 14 is used in connection with let.- ter sheets of the short type. v

The adjustable indicator 5 is provided with a scale 15, numbered from 1 to 10 beginning with the line just below the lower edge of the stop 6. This scale 15 is espe cially advantageous when it is desired to leave a wider margin at the end of the sheet than is ordinarily left, or when sheets of a shorter length than the standard are used. The scale 15 is-movable with the stop 6 and will therefore keep the operator advised as to the nearness of the bottom of the sheet or the top of the margin.

The legend Legal is placed at the top of the stop 6 and a scale 16 is arranged below the legend and beginning on the line next below the legend, and is numbered 1 to 10. This scale'16- is for use in connection with Legal length paper, the finger grip 11 acting as a stop for the upper end of the legal sheet.

The lower end of the body 1 is preferably made to conform to the contour of the'upper end of the paper rest and is provided with a'rolled portion 17, which is adapted to slide under the rolled portion 18 of the paper rest 19, such as is used upon the Underwood machine. The rolled portion 17 is provided with a projectinglip 20, which extends under the paper rest 19, and ;acts as a brace for the margin indicator. The rolled portion terminates at its opposite end in a folded portion, which fits snugly around the outer edge of the rolled portion 18, as indicated at 21. The folded portion 21 terminates in an offset portion 22, which is formed directly upon the lower end of the body 1. In placing the device upon a machine, the rolled portion 17 is inserted under the rolled portion 18, endwise of the paper rest, thereby rigidly holding the. margin indicator in engagement with the paper rest. A modified form of the means for attach: ing the indicator to the paper rest, is shown in Fig. 8, wherein the] body 1 is provided with a rearwardly extending folded portion 23, which is adapted to fit over a straight type of paper rest. If desired, a clamping screw may be used for clamping the folded portion 23 to the paper-rest, as shown at 24. Fig. 6 discloses the adjustable indicator 5 as provided with spring tongues 25 extending transversely of the indicator 5, the tongues 25 constituting a frictional grip against the rear face of the body 1. I Fig. 9 discloses a further modified form for holding the adjustable indicator against slipping, wherein spring tongues 26 are formed in the flanges 3*, for engaging the sition to be readily viewed by the operator.

The indicator is adapted to extend at substantially the same angle as the paper rest and constitutes a' continuation'thereof.

When the stop 6 is in a predetermined or standard position, by predetermined measurement, a standard letterhead of the size 8 x 11" will feed through the typewriter, and when the top of the sheet reaches the lower edge 10, the typist will have reached his last line on said page. scale 13 is used with paper of the. size above mentioned. VVhenthe standard sheet used is 8" x 102;, the scale 14 is used in a similar manner. When a legal size sheet, 8%" x13, is used, the scale 16 will determine the margin at the bottom of the sheet. Having established by predetermined measurements, the standard position .of the indicator, it will be seen that, after the top Thieof the paper sheet reaches the lower line of either scale 13, 14, 15, or 16, the typist is warned, line by line, as he proceeds, of the exact number of lines yet remaining to be writtenon the sheet. i

It should be understood that the operator may adjust the device to any desired width of margin, to-wit: If the typist desires to stop the typewritten page, say, five lines from bottom of sheet, he would slide the stop 6 downward so that the lower edge- .typist.

line of stop 6 would be immediately over and parallel with line Under these conditions, the indicator or strip 5 would register, line by line, the number of typewritten lines yet remaining to be written before the desired last line is reached by the It should also be understood that certain detail changes may be made in the construction of the device without departing fro-m the spirit of the invention, so long as these changes fall without the scope of the appended claims.
